本明細書に使用されているように「喫煙材料」には、加熱すると揮発成分を出す任意の材料および任意のタバコ含有材料が含まれ、例えばタバコ、タバコ派生物、拡張タバコ、再生タバコ、またはタバコ代替品の１種以上を含んでもよい。 As used herein, "smoking material" includes any material that emits a volatile component when heated and any tobacco-containing material, such as tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or It may include one or more tobacco substitutes.
喫煙材料を加熱する器具１はエネルギー源２、加熱器３、および加熱室４を備える。エネルギー源２は、リチウムイオン電池、ニッケル電池、アルカリ電池および／または同様の電池を備えてもよく、加熱器３に電気的に接続されていて必要時に電気エネルギーを加熱器３に供給する。加熱室４は喫煙材料５を収容するように構成されており、加熱室４内で喫煙材料５を加熱できるようになっている。例えば、加熱器３に隣接して加熱室４を配置し、その中の喫煙材料５を加熱器３の熱エネルギーで燃焼させずに加熱して喫煙材料５の芳香成分およびニコチンを揮発させるようにしてもよい。吸い口６が設けられており、使用者が器具１を使用中に蒸発した成分をこの吸い口６を介して吸入することができる。喫煙材料５はタバコ配合物を含んでいてもよい。 The appliance 1 for heating a smoking material comprises an energy source 2, a heater 3 and a heating chamber 4. The energy source 2 may comprise a lithium-ion battery, a nickel battery, an alkaline battery and/or a similar battery and is electrically connected to the heater 3 to supply electric energy to the heater 3 when needed. The heating chamber 4 is configured to contain the smoking material 5, and the smoking material 5 can be heated in the heating chamber 4. For example, a heating chamber 4 is disposed adjacent to the heater 3, and the smoking material 5 therein is heated without being burned by the heat energy of the heater 3 so that the aroma component and nicotine of the smoking material 5 are volatilized. May be. The mouthpiece 6 is provided so that the user can inhale the components evaporated during use of the device 1 through the mouthpiece 6. The smoking material 5 may include a tobacco formulation.
器具１のエネルギー源２および加熱器３のような要素を、ハウジング７に収容してもよい。図１に示す様に、ハウジング７はほぼ円筒状の管を構成し、その第１の端部８の方にエネルギー源２を、その反対側である第２の端部９の方に加熱器３および加熱室４を配置している。エネルギー源２および加熱器３はハウジング７の長手方向軸に沿って延びている。例えば図１に示す様に、エネルギー源２および加熱器３をハウジング７の中心長手方向軸に沿って実質的に端と端が接した配置に整列させ、エネルギー源２の端面と加熱器３の端面とが向かい合うようにすることができる。ハウジング７の長さは約１３０ｍｍでもよく、エネルギー源の長さは約５９ｍｍでもよく、加熱器３および加熱領域４の長さは約５０ｍｍでもよい。ハウジング７の直径は約１５〜約１８ｍｍでもよい。例えば、ハウジングの第１の端部８の直径は１８ｍｍでもよく、ハウジングの第２の端部９の吸い口６の直径は１５ｍｍでもよい。加熱器３の直径は約２．０〜約６．０ｍｍでもよい。加熱器３の直径は例えば約４．０〜約４．５ｍｍでもよく、または約２．０〜約３．０ｍｍでもよい。これらの範囲以外の加熱器の直径および厚みを代わりに用いてもよい。例えば、ハウジング７の直径および器具１全体の大きさを、後述するフィルム状の加熱器３および真空断熱部１８を用いて大幅に小さくすることができる。加熱室４の奥行きは約５ｍｍでもよく、加熱室４はその外表面で約１０ｍｍの外径を有してもよい。エネルギー源２の直径は約１４．０〜約１５．０ｍｍ、例えば１４．６ｍｍでもよい。しかし、さらに小さい直径のエネルギー源２を代わりに用いることもできる。 Elements such as the energy source 2 and the heater 3 of the appliance 1 may be housed in the housing 7. As shown in FIG. 1, the housing 7 comprises a substantially cylindrical tube, the energy source 2 being towards the first end 8 thereof and the heater 2 being opposite to the second end 9. 3 and heating chamber 4 are arranged. The energy source 2 and the heater 3 extend along the longitudinal axis of the housing 7. For example, as shown in FIG. 1, the energy source 2 and the heater 3 are aligned in a substantially end-to-end arrangement along the central longitudinal axis of the housing 7 such that the end face of the energy source 2 and the heater 3 are aligned. The end faces can face each other. The length of the housing 7 may be about 130 mm, the length of the energy source may be about 59 mm, and the length of the heater 3 and the heating area 4 may be about 50 mm. The diameter of the housing 7 may be about 15 to about 18 mm. For example, the diameter of the first end 8 of the housing may be 18 mm and the diameter of the mouthpiece 6 of the second end 9 of the housing may be 15 mm. The heater 3 may have a diameter of about 2.0 to about 6.0 mm. The diameter of the heater 3 may be, for example, about 4.0 to about 4.5 mm, or about 2.0 to about 3.0 mm. Heater diameters and thicknesses outside these ranges may be used instead. For example, the diameter of the housing 7 and the overall size of the device 1 can be significantly reduced by using a film-shaped heater 3 and a vacuum heat insulating section 18 described later. The depth of the heating chamber 4 may be about 5 mm and the heating chamber 4 may have an outer diameter on its outer surface of about 10 mm. The diameter of the energy source 2 may be about 14.0 to about 15.0 mm, for example 14.6 mm. However, a smaller diameter energy source 2 could be used instead.
エネルギー源２と加熱器３の間に断熱部を設けて、一方から他方へ熱が直接伝わらないようにしてもよい。吸い口６をハウジング７の第２の端部９に加熱室４および喫煙材料５に隣接して配置することができる。ハウジング７は、使用者が使用中に器具１を握るのに適しているため、使用者が喫煙材料の揮発成分を器具１の吸い口６から吸入することができる。 A heat insulating portion may be provided between the energy source 2 and the heater 3 so that heat is not directly transmitted from one side to the other side. A mouthpiece 6 can be arranged at the second end 9 of the housing 7 adjacent to the heating chamber 4 and the smoking material 5. The housing 7 is suitable for the user to grip the device 1 during use, so that the user can inhale the volatile constituents of the smoking material through the mouthpiece 6 of the device 1.
加熱器３はフィルム状のポリイミド加熱器３のようなフィルム加熱器３を備えてもよい。一具体例はカプトン（Ｋａｐｔｏｎ（登録商標））ポリイミド加熱器３である。代わりに他の材料を用いることもできる。フィルム加熱器３は引張強度および対裂断抵抗が大きい。加熱器３の絶縁強度は約１０００ＶＡＣでもよい。フィルム加熱器３は厚みが薄く、例えば１ｍｍ未満であり、他の種類の加熱器を使用するよりも器具１の小型化に大きな貢献をすることができる。フィルム３の一例示的な厚みは約０．２ｍｍであるが、厚み寸法がさらに薄いおよび厚い加熱器３を代わりに用いることができる。例えば、フィルム加熱器３の厚みは約０.０００２ｍｍまで薄くてもよい。加熱器３の出力は約５〜約８Ｗ／ｃｍ２でもよいが、この出力はさらに小さくてもよく、必要ならこの出力を経時的に制御してもよい。フィルム加熱器３は必要なら透明でもよく、そのようにすると内部構造を容易に検査することができる。そのように検査が簡単であると、品質管理および保守作業に便利な場合がある。加熱室４内の喫煙材料を加熱するために、フィルム加熱器３に、エッチングされたフィルム状の加熱要素を１個以上組み込んでもよい。加熱器３の作動温度は例えば最大約２６０℃でもよい。器具１は加熱器３の温度制御に用いる抵抗温度検出器（ＲＴＤ）または熱電対を備えてもよい。加熱器３の表面に感知器を取り付けてもよい。感知器は抵抗の測定値を制御器１２に送るように構成されており、制御器１２によって加熱器３の温度を維持または必要に応じて調整することができるようになっている。例えば制御器１２は加熱器３の電源を入り切りして所定時間ある温度に維持してもよく、またはその温度をある加熱方法に従って変化させてもよい。制御器１２および具体的な加熱方法の例を以下にさらに詳細に述べる。フィルム加熱器３の質量は小さいため、このフィルム加熱器３を使用して器具１の全質量を容易に低減することができる。 The heater 3 may include a film heater 3 such as a film-shaped polyimide heater 3. One specific example is a Kapton® polyimide heater 3. Other materials may be used instead. The film heater 3 has high tensile strength and resistance to tearing. The insulation strength of the heater 3 may be about 1000 VAC. The film heater 3 has a small thickness, for example, less than 1 mm, and can greatly contribute to miniaturization of the device 1 as compared with the case of using other types of heaters. One exemplary thickness of film 3 is about 0.2 mm, but heaters 3 with thinner and thicker thickness dimensions can be used instead. For example, the thickness of the film heater 3 may be as thin as about 0.0002 mm. The output of the heater 3 may be from about 5 to about 8 W/cm 2 , but this output may be smaller and may be controlled over time if desired. The film heater 3 may be transparent if desired, so that the internal structure can be easily inspected. Such easy inspection may be convenient for quality control and maintenance work. To heat the smoking material in the heating chamber 4, the film heater 3 may incorporate one or more heating elements in the form of etched films. The operating temperature of the heater 3 may be, for example, up to about 260°C. The instrument 1 may include a resistance temperature detector (RTD) or thermocouple used to control the temperature of the heater 3. A sensor may be attached to the surface of the heater 3. The sensor is configured to send a resistance measurement to the controller 12, which allows the temperature of the heater 3 to be maintained or adjusted as needed. For example, the controller 12 may turn on and off the heater 3 to maintain a certain temperature for a predetermined time, or change the temperature according to a certain heating method. Examples of controller 12 and specific heating methods are described in further detail below. Since the mass of the film heater 3 is small, this film heater 3 can be used to easily reduce the total mass of the device 1.
図１に示す様に、加熱器３は別々の加熱領域１０を複数備えてもよい。複数の加熱領域１０は互いに独立して作動可能で、異なる領域１０を異なる時間に活性化して喫煙材料５を加熱することができるようになっていてもよい。加熱領域１０は加熱器３の中にどのような幾何学的な配置で配置されてもよい。しかし図１に示す具体例では、加熱領域１０は、その１つ１つが主に喫煙材料５の異なる領域を個別に加熱できるように、加熱器３内に幾何学的に配置されている。 As shown in FIG. 1, the heater 3 may include a plurality of separate heating regions 10. A plurality of heating regions 10 are operable independently of each other, it may be made to be able to heat the smoking material 5 to activate the different regions 10 different times. The heating area 10 may be arranged in the heater 3 in any geometrical arrangement. However, in the embodiment shown in FIG. 1, the heating zones 10 are arranged geometrically in the heater 3 so that each one is able to mainly heat different zones of the smoking material 5 individually.
例えば図１および２を参照すると、加熱器３は軸方向に実質的に細長い配置に整列された複数の加熱領域１０を備えてもよい。複数の領域１０はそれぞれが加熱器３の個々の要素を構成してもよい。例えば複数の加熱領域１０は全てが加熱器３の長手方向軸に沿って互いに整列していて、加熱器３の長さに沿って複数の独立した加熱区域を提供していてもよい。 For example, referring to FIGS. 1 and 2, the heater 3 may include a plurality of heating regions 10 that are axially aligned in a substantially elongated arrangement. Each of the plurality of regions 10 may constitute an individual element of the heater 3. For example, the plurality of heating zones 10 may all be aligned with each other along the longitudinal axis of the heater 3 to provide a plurality of independent heating zones along the length of the heater 3.
図１を参照すると、各加熱領域１０は中空の加熱筒１０を構成してもよい。この加熱筒１０は加熱器３の全体の長さより大幅に短い有限長の環１０でもよい。複数の加熱領域１０を軸方向に整列させて配置することによって加熱室４の外側が規定され、加熱領域１０が加熱室４内に置かれた喫煙材料５を加熱するように構成される。熱は主に内向きに加熱室４の中心長手方向軸に向かって加えられる。複数の加熱領域１０は互いにその半径方向の面すなわち横断面を向き合わせて、加熱器３の長さに沿って配置されている。各加熱領域１０の横断面とそれらの隣り合う加熱領域１０の横断面とは、図１に示し以下に述べるように断熱部１８によって分離されていてもよい。 Referring to FIG. 1, each heating region 10 may form a hollow heating cylinder 10. The heating cylinder 10 may be a ring 10 having a finite length that is significantly shorter than the entire length of the heater 3. The outside of the heating chamber 4 is defined by arranging the plurality of heating regions 10 in axial alignment, and the heating regions 10 are configured to heat the smoking material 5 placed in the heating chamber 4. The heat is applied mainly inwardly towards the central longitudinal axis of the heating chamber 4. The plurality of heating regions 10 are arranged along the length of the heater 3, with their radial surfaces, ie, their cross-sections, facing each other. The cross section of each heating region 10 and the cross sections of their adjacent heating regions 10 may be separated by a heat insulating section 18, as shown in FIG. 1 and described below.
または図２に示す様に、加熱器３をハウジング７の中心領域に配置してもよく、加熱器３の長手方向表面の周りに加熱室４および喫煙材料５を配置してもよい。この配列では、加熱器３が放射する熱エネルギーは加熱器３の長手方向表面から外向きに移動し、加熱室４および喫煙材料５に入る。 Alternatively, as shown in FIG. 2, the heater 3 may be arranged in the central region of the housing 7 and the heating chamber 4 and the smoking material 5 may be arranged around the longitudinal surface of the heater 3. In this arrangement, the thermal energy emitted by the heater 3 travels outwards from the longitudinal surface of the heater 3 and enters the heating chamber 4 and the smoking material 5.
加熱領域１０はそれぞれが加熱器３の独立した要素を構成してもよい。図１および２に示す様に、各加熱領域１０は、加熱器３全体の長さよりも大幅に短い有限長を有する加熱筒１０を構成してもよい。しかし、加熱器３の他の構成を代わりに用いることも可能であり、つまり円筒断面をしたフィルム加熱器３を用いる必要もなくなる。複数の加熱領域１０を、それらの横断面が互いに加熱器３の長さに沿って向き合うように整列させてもよい。各領域１０の横断面がその隣の領域１０の横断面に接触していてもよい。あるいは領域１０の横断面の間に断熱部または熱反射層を存在させて、領域１０の１つ１つから放射される熱エネルギーが隣り合う領域１０を実質的に加熱せず、主に加熱室４および喫煙材料５に移動するようにしてもよい。各加熱領域１０は他の領域１０と実質的に同じ寸法を有してもよい。 The heating areas 10 may each constitute an independent element of the heater 3. As shown in FIGS. 1 and 2, each heating region 10 may constitute a heating cylinder 10 having a finite length that is significantly shorter than the length of the entire heater 3. However, it is also possible to use another configuration of the heater 3 instead, that is, it is not necessary to use the film heater 3 having a cylindrical cross section. The plurality of heating regions 10 may be aligned such that their cross-sections face each other along the length of the heater 3. The cross section of each region 10 may be in contact with the cross section of the adjacent region 10. Alternatively, a heat insulating portion or a heat reflecting layer is present between the cross sections of the regions 10 so that the heat energy emitted from each of the regions 10 does not substantially heat the adjacent regions 10, and the heating chamber is mainly used. 4 and the smoking material 5 may be moved. Each heating zone 10 may have substantially the same dimensions as the other zones 10.
この方法では、加熱領域１０の特定の１つを活性化すると、その加熱領域１０は例えば半径方向の隣に配置された喫煙材料５に熱エネルギーを供給し、残りの喫煙材料５を実質的に加熱しない。図２を参照すると、喫煙材料５の加熱領域は、活性化されている加熱領域１０の周りに配置された環状の喫煙材料５を構成してもよい。したがって喫煙材料５の例えば環状または実質的に中実円筒状の複数部分を別々に加熱することができる。このとき、それぞれの部分は複数の加熱領域１０の特定の１つに直接隣接して配置された喫煙材料５に相当し、喫煙材料５全体の塊よりも大幅に少ない質量および体積を有する。 In this way, when a particular one of the heating zones 10 is activated , that heating zone 10 supplies thermal energy to, for example, a radially adjacent smoking material 5 and substantially removes the remaining smoking material 5. Do not heat. Referring to FIG. 2, the heating area of the smoking material 5 may constitute an annular smoking material 5 arranged around the heating area 10 being activated . It is thus possible to separately heat several parts of the smoking material 5, for example annular or substantially solid cylindrical. Each part then corresponds to the smoking material 5 arranged directly adjacent to a particular one of the heating zones 10 and has a mass and volume which is considerably less than the mass of the entire smoking material 5.
さらにまたは代わりに、加熱器３は、加熱器３の中心長手方向軸周りの異なる複数の場所に配置され細長く長手方向に延びる加熱領域１０を備えてもよい。複数の加熱領域１０は長さが異なってもまたは実質的に同じ長さでもよく、それぞれが加熱器３の実質的に全長に沿って延びるようになっている。 Additionally or alternatively, the heater 3 may include elongated elongated longitudinal heating regions 10 located at different locations about the central longitudinal axis of the heater 3. The plurality of heating regions 10 may be of different lengths or of substantially the same length, each extending substantially along the entire length of the heater 3.
喫煙材料５の加熱部分は、長手方向の加熱領域１０に平行かつそれに直接隣接して横たわる喫煙材料５の長手方向の部分を構成しもよい。したがって先に説明したように、喫煙材料５の複数の部分を別々に加熱することができる。 The heated portion of the smoking material 5 may comprise the longitudinal portion of the smoking material 5 lying parallel to and directly adjacent to the longitudinal heating region 10. Thus, as explained above, multiple parts of the smoking material 5 can be heated separately.
さらに後述のように、複数の加熱領域１０をそれぞれ別々にかつ選択的に活性化することができる。 Further, as will be described later, each of the plurality of heating regions 10 can be separately and selectively activated .
喫煙材料５を、加熱室４に挿入可能なカートリッジ１１上に構成してもよい。例えば図１に示す様に、カートリッジ１１は加熱器３の凹みに収まる円筒のような実質的に中実の喫煙材料５の塊を構成することができる。この構成では、喫煙材料塊の外面が加熱器３と向かい合う。あるいは図２に示す様に、カートリッジ１１は加熱器３の周りに挿入可能な喫煙材料の管１１を構成することができ、喫煙材料の管１１の内面が加熱器３の長手方向表面と向き合うようになる。喫煙材料の管１１は中空でもよい。管１１の中空中心部の直径は、管１１が加熱器３の周りにぴったり収まるように加熱器３の直径すなわち横断寸法と実質的に同じでもまたはそれよりも僅かに大きくてもよい。カートリッジ１１の長さは加熱器３の長さとほぼ同じでもよく、加熱器３がカートリッジ１１をその全長に沿って加熱できるようになっている。 The smoking material 5 may be constructed on a cartridge 11 insertable into the heating chamber 4. For example, as shown in FIG. 1, the cartridge 11 may comprise a substantially solid mass of smoking material 5, such as a cylinder that fits within the recess of the heater 3. In this configuration, the outer surface of the smoking material mass faces the heater 3. Alternatively, as shown in FIG. 2, the cartridge 11 may constitute a tube 11 of smoking material insertable around the heater 3, such that the inner surface of the tube 11 of smoking material faces the longitudinal surface of the heater 3. become. The tube 11 of smoking material may be hollow. The diameter of the hollow center of the tube 11 may be substantially the same as or slightly larger than the diameter or transverse dimension of the heater 3 so that the tube 11 fits around the heater 3. The length of the cartridge 11 may be substantially the same as the length of the heater 3 so that the heater 3 can heat the cartridge 11 along its entire length.
器具１のハウジング７は開口を備え、その開口を通ってカートリッジ１１を加熱室４に挿入することができてもよい。開口は例えば、ハウジングの第２の端部９に配置された開口を構成し、その開口にカートリッジ１１を挿入し加熱室４内に直接押し込むことができるようになっていてもよい。好ましくは、器具１の使用中はこの開口は喫煙材料５を加熱するために閉じられる。あるいはハウジング７の一部は第２の端部９において器具１から取り外し自在であり、喫煙材料５を加熱室４に挿入することができるようになっている。必要なら使用者が操作可能な内部機構のような喫煙材料取り外し装置を器具１に設けてもよい。この取り外し装置は使用済みの喫煙材料５を加熱器３から滑らせて外す、ならびに／あるいは分離するように構成されている。例えば使用済みの喫煙材料５をハウジング７の開口から押し戻してもよい。必要ならその後新しいカートリッジ１１を挿入することができる。 The housing 7 of the device 1 may be provided with an opening through which the cartridge 11 can be inserted into the heating chamber 4. The opening may, for example, constitute an opening arranged in the second end 9 of the housing, into which the cartridge 11 can be inserted and pushed directly into the heating chamber 4. Preferably, during use of the device 1, this opening is closed to heat the smoking material 5. Alternatively, part of the housing 7 is removable from the device 1 at the second end 9 so that the smoking material 5 can be inserted into the heating chamber 4. If desired, the device 1 may be provided with a smoking material removal device such as a user-operable internal mechanism. This removal device is configured to slide the used smoking material 5 out of the heater 3 and/or to separate it. For example, the used smoking material 5 may be pushed back from the opening of the housing 7. If necessary, a new cartridge 11 can then be inserted.
先に述べたように、器具１は器具１の作動を制御するように構成された制御器１２例えば超小型制御器１２を備えてもよい。制御器１２は器具１のエネルギー源２および加熱器３のような他の要素に電気的に接続されており、信号の送受信によって他の要素を制御できるようになっている。具体的には、制御器１２は加熱器３の活性化を制御して喫煙材料５を加熱するように構成されている。例えば、制御器１２は加熱器３を活性化するように構成され、これには使用者が器具１の吸い口６を吸引すると１つ以上の加熱領域１０を選択的に活性化することを含んでもよい。その際、制御器１２は吸入感知器１３と適切な連通結合を介して繋がっていてもよい。吸入感知器１３は吸い口６で吸引が発生したときを検出するように構成されており、検出すると吸引を示す信号を制御器１２に送るように構成されている。電子信号を用いてもよい。制御器１２は吸入感知器１３からの信号に対し加熱器３を活性化して応答し、そうやって喫煙材料５を加熱してもよい。しかし、加熱器３の活性化に吸入感知器１３を用いることは必須ではなく、加熱器３を活性化する刺激を供給する他の代替手段を用いることができる。例えば制御器１２は別の種類の活性化刺激、例えば使用者が操作できる作動装置の作動に応じて加熱器３を活性化してもよい。その結果、加熱中に放出された揮発成分を使用者が吸い口６から吸入することができる。制御器１２は、ハウジング７内の適切であればどの位置に配置してもよい。一例示的位置は図４に示すようにエネルギー源２と加熱器３／加熱室４の間である。 As mentioned above, the instrument 1 may comprise a controller 12 configured to control the operation of the instrument 1, eg a micro controller 12. The controller 12 is electrically connected to other elements such as the energy source 2 and the heater 3 of the appliance 1 so that the other elements can be controlled by transmitting and receiving signals. Specifically, the controller 12 is configured to control activation of the heater 3 to heat the smoking material 5. For example, the controller 12 is configured to activate the heater 3, which includes selectively activating one or more heating regions 10 when a user inhales the mouthpiece 6 of the device 1. But it's okay. The controller 12 may then be connected to the inhalation sensor 13 via a suitable communication connection. The inhalation sensor 13 is configured to detect when suction occurs at the mouthpiece 6, and when detected, is configured to send a signal indicating suction to the controller 12. Electronic signals may be used. The controller 12 may respond to the signal from the inhalation sensor 13 by activating the heater 3 and thus heating the smoking material 5. However, the use of the suction sensor 13 to the activation of the heater 3 is not essential, it is possible to use other alternative means of supplying the stimulus to activate the heater 3. For example, the controller 12 may activate the heater 3 in response to another type of activation stimulus, such as activation of a user actuable actuating device. As a result, the user can inhale the volatile components released during heating from the mouthpiece 6. The controller 12 may be located in any suitable location within the housing 7. One exemplary location is between the energy source 2 and the heater 3/heating chamber 4 as shown in FIG.
加熱器３が上記のように２つ以上の加熱領域１０を備える場合、加熱領域１０を所定の順序または様式で活性化するように制御器１２を構成してもよい。例えば、複数の加熱領域１０を加熱室４に沿って、または加熱室４の周りで連続的に活性化するように制御器１２を構成してもよい。各加熱領域１０を、吸入感知器１３が吸引を検出するのに応答して活性化してもよく、または後述のような別の方法で活性化してもよい。 If the heater 3 comprises more than one heating zone 10 as described above, the controller 12 may be configured to activate the heating zones 10 in a predetermined order or manner. For example, controller 12 may be configured to continuously activate a plurality of heating regions 10 along or around heating chamber 4. Each heating region 10 may be activated in response to inhalation sensor 13 detecting inhalation, or may be activated in another manner as described below.
図５を参照すると、一例示的加熱方法は、第１の吸引のような活性化刺激が検知される第１の工程Ｓ１を備え、その後第２の工程Ｓ２が続いてもよい。第２の工程Ｓ２では、第１の吸引または他の活性化刺激に応じて喫煙材料５の第１の部分が加熱される。第３の工程Ｓ３では、封止可能な吸排気弁２４を開けて空気を加熱室４から吸引し、吸い口６から器具１の外に出せるようにしてもよい。第４の工程で弁２４は閉じられる。これらの弁２４についてはこの後、図２０で詳細に述べる。第５のＳ５工程、第６のＳ６工程、第７のＳ７工程、および第８のＳ８工程では、第２の活性化刺激例えば第２の吸引に応じて、加熱室吸排気弁２４をそれに合わせて開放ならびに閉鎖することによって喫煙材料５の第２の部分を加熱してもよい。第９のＳ９工程、第１０のＳ１０工程、第１１のＳ１１工程、および第１２のＳ１２工程では、第３の活性化刺激例えば第３の吸引に応じて、加熱室吸排気弁２４をそれに合わせて開放ならびに閉鎖することによって喫煙材料５の第３の部分を加熱してもよく、同様に続く。上記のように、吸入感知器１３以外の代替手段を使用することができる。例えば器具１の使用者が制御スイッチを作動させて新規に吸引していることを示してもよい。この方法の場合、新規の吸引ごとに喫煙材料５の新規の部分を加熱してニコチンおよび芳香成分を揮発させてもよい。喫煙材料５の加熱領域１０の数および／または別々に加熱可能な部分の数はカートリッジ１１の予定の吸引数と一致していてもよい。あるいは別々に加熱することが可能な各喫煙材料部分５を対応した加熱領域１０によって、複数回の吸引、例えば２回、３回、または４回の吸引ごとに加熱し、前の喫煙材料部分の加熱中に複数回の吸引が終了した場合のみ、喫煙材料５の新規部分を加熱するようにしてもよい。 Referring to FIG. 5, one exemplary heating method may include a first step S1 in which an activation stimulus, such as a first aspiration, is detected, followed by a second step S2. In the second step S2, the first portion of the smoking material 5 is heated in response to the first suction or other activation stimulus. In the third step S3, the sealable intake/exhaust valve 24 may be opened to suck the air from the heating chamber 4 and let the air out of the device 1 through the suction port 6. In the fourth step, the valve 24 is closed. These valves 24 will be described in detail later in FIG. In the fifth S5 step, the sixth S6 step, the seventh S7 step, and the eighth S8 step, the heating chamber intake/exhaust valve 24 is adjusted to that in response to the second activation stimulus, for example, the second suction. The second portion of the smoking material 5 may be heated by opening and closing it. In the ninth step S9, the tenth step S10, the eleventh step S11, and the twelfth step S12, the heating chamber intake/exhaust valve 24 is adjusted to that in response to the third activation stimulus, for example, the third suction. The third portion of the smoking material 5 may be heated by opening and closing the same, and so on. As mentioned above, alternative means other than the inhalation sensor 13 can be used. For example, the user of the device 1 may activate the control switch to indicate that new suction is being performed. In the case of this method, a new portion of the smoking material 5 may be heated for each new suction to volatilize the nicotine and the aroma component. The number of heating zones 10 and/or the number of separately heatable parts of the smoking material 5 may match the planned number of suctions of the cartridge 11. Alternatively, each smoking material part 5, which can be heated separately, is heated by a corresponding heating area 10 after every several suctions, for example every two, three, or four suctions, and the previous smoking material part is heated. The new portion of the smoking material 5 may be heated only when a plurality of suctions are completed during heating.
各加熱領域１０を個々の吸引に応じて活性化する代わりに、吸い口６の最初の１回の吸引に応じて複数の加熱領域１０を連続的に代わる代わる活性化してもよい。例えば、特定の喫煙材料カートリッジ１１の予定吸引時間の間中、複数の加熱領域１０を定期的な所定の間隔で活性化させてもよい。吸引時間は例えば約１〜約４分でもよい。したがって図５に示す少なくとも第５の工程Ｓ５および第９の工程Ｓ９は任意である。各加熱領域１０を１回または複数回の吸引時間に相当する所定の時間作動させて、別々に加熱可能な対応する喫煙材料部分５をこの時間だけ加熱するようにしてもよい。あるカートリッジ１１の全ての加熱領域１０が活性化したら使用者にそのカートリッジ１１の交換の必要性を示すように制御器１２を構成してもよい。制御器１２は例えばハウジング７の外面の表示灯を点灯させてもよい。 Instead of activating each heating region 10 in response to an individual suction, a plurality of heating regions 10 may be activated successively in succession in response to the first single suction of the mouthpiece 6. For example, the plurality of heating regions 10 may be activated at regular, predetermined intervals during the planned suction time of a particular smoking material cartridge 11. The suction time may be, for example, about 1 to about 4 minutes. Therefore, at least the fifth step S5 and the ninth step S9 shown in FIG. 5 are optional. Each heating region 10 may be operated for a predetermined time corresponding to one or more suction times, so that the corresponding separately heatable smoking material parts 5 are heated for this time. The controller 12 may be configured to indicate to the user the need to replace the cartridge 11 once all heating areas 10 of the cartridge 11 have been activated . The controller 12 may turn on an indicator light on the outer surface of the housing 7, for example.
当然だが、加熱器３全体を活性化するのではなく個々の加熱領域１０を順次活性化することで、喫煙材料５の加熱に要するエネルギーが、カートリッジ１１の全吸引時間中ずっと加熱器３が全て活性化される場合に必要なエネルギーよりも低減される。したがってエネルギー源２の必要最大出力も低減される。すなわち、より小型軽量のエネルギー源２を器具１に搭載することができることになる。 Unsurprisingly, by sequentially activating individual heating areas 10 instead of activating the entire heater 3, the energy required for heating the smoking material 5, the total suction time in much the heater 3 is all cartridges 11 It is less than the energy required when activated . Therefore, the required maximum output of the energy source 2 is also reduced. That is, the smaller and lighter energy source 2 can be mounted on the device 1.
吸引と吸引の間は加熱器３を停止するように、または加熱器３に供給される電力を減らすように制御器１２を構成してもよい。こうすることによってエネルギーが節約され、エネルギー源２の持続時間が延びる。例えば使用者が器具１のスイッチを入れると、または使用者が唇を吸い口６に接触させるのを検出するというような何らかの他の刺激に応じて、加熱器３または次の加熱領域１０を用いて喫煙材料５を加熱し、部分的に活性化させるように制御器１２を構成し、喫煙材料５が成分の揮発のために予備加熱されるようにしてもよい。この不完全な活性化では、喫煙材料５はニコチンを揮発させるのに十分な温度までは熱くならない。適切な温度は約１００℃にすることができる。吸入感知器１３による吸引の検出に応じて、制御器１２は当該加熱器３または当該加熱領域１０で喫煙材料５をさらに加熱して、使用者が吸引するニコチンおよび他の芳香成分を瞬時に揮発させることができる。喫煙材料５がタバコを含む場合、ニコチンおよび他の芳香成分の揮発に適切な温度は１５０〜２５０℃でもよい。したがって、一例示的完全作動温度は２５０℃である。必要なら、喫煙材料５を揮発温度まで加熱するのに用いられる最大電流の供給に電気二重層コンデンサー（super-capacitor）を用いることができる。適切な加熱様式の一具体例を図７に示す。ここでは、複数の最大値はそれぞれ別の加熱領域１０の完全活性化を表してもよい。図からわかるように、喫煙材料５はほぼ吸引時間（この具体例では２秒）だけ揮発温度に維持されている。 The controller 12 may be configured to stop the heater 3 between suctions or reduce the power supplied to the heater 3. This saves energy and extends the duration of the energy source 2. Using the heater 3 or the next heating area 10 in response to some other stimulus, for example when the user switches on the appliance 1 or detects that the user touches his lips with the mouthpiece 6. The controller 12 may be configured to heat and partially activate the smoking material 5 so that the smoking material 5 is preheated for volatilization of the components. With this incomplete activation, the smoking material 5 does not heat up to a temperature sufficient to volatilize the nicotine. A suitable temperature can be about 100°C. In response to the detection of inhalation by the inhalation sensor 13, the controller 12 further heats the smoking material 5 in the heater 3 or the heating region 10 to instantly volatilize nicotine and other aroma components inhaled by the user. Can be made. If the smoking material 5 comprises tobacco, a suitable temperature for volatilization of nicotine and other aroma components may be 150-250°C. Thus, one exemplary full operating temperature is 250°C. If desired, an electric double layer capacitor can be used to supply the maximum current used to heat the smoking material 5 to the volatilization temperature. One specific example of a suitable heating mode is shown in FIG. Here, the plurality of maximum values may represent the complete activation of different heating zones 10. As can be seen from the figure, the smoking material 5 is maintained at the volatilization temperature for almost the suction time (2 seconds in this specific example).
加熱器３の３つの例示的作動形態について以下に述べる。 Three exemplary modes of operation of the heater 3 are described below.
第１の作動形態では、ある加熱領域１０が完全に活性化している間、加熱器の他の加熱領域１０は全て停止している。したがって、新たな加熱領域１０が活性化すると、前の加熱領域は停止する。電力は活性化した領域１０にのみ供給される。 In the first mode of operation, one heating zone 10 is fully activated while all other heating zones 10 of the heater are deactivated. Therefore, when the new heating area 10 is activated , the previous heating area is stopped. Power is supplied only to the activated area 10.
代わって第２の作動形態では、ある加熱領域１０が完全に活性化している間、他の加熱領域１０の１つ以上が不完全に活性化していてもよい。上記の１つ以上の他の加熱領域１０の不完全な活性化は、それらの加熱領域１０をある温度までしか加熱しないことを含んでもよく、その温度では、加熱室４内の喫煙材料５から揮発した成分、例えばニコチンを実質的に濃縮させない。不完全に活性化した加熱領域１０の温度は完全に活性化している加熱領域１０の温度未満である。不完全に活性化した領域１０に隣接して配置されている喫煙材料５は、その成分を揮発させるほどの温度までは加熱されない。 Alternatively, in the second mode of operation, one heating zone 10 may be fully activated while one or more of the other heating zones 10 is incompletely activated . The incomplete activation of one or more other heating zones 10 as described above may include heating those heating zones 10 only to a temperature at which the smoking material 5 in the heating chamber 4 is removed. Volatile components such as nicotine are not substantially concentrated. The temperature of the incompletely activated heating zone 10 is below the temperature of the fully activated heating zone 10. The smoking material 5 located adjacent to the incompletely activated region 10 is not heated to a temperature sufficient to volatilize its constituents.
代わって第３の作動形態では、ある加熱領域１０が活性化すると、その加熱領域１０は加熱器３のスイッチが切られるまで完全に活性化したままになる。したがってカートリッジ１１からの吸引中はより多数の加熱領域１０が活性化されるため、加熱器３に供給される電力は徐々に増える。上述の第２の形態と同様に加熱領域１０を連続的に活性化することによって、加熱室４内の喫煙材料５から揮発したニコチンのような成分の濃縮が実質的に抑制される。 Alternatively, in the third mode of operation, when a heating zone 10 is activated, it remains fully activated until the heater 3 is switched off. Therefore, during suction from the cartridge 11, a larger number of heating regions 10 are activated, so that the electric power supplied to the heater 3 gradually increases. By continuously activating the heating region 10 as in the second embodiment described above, concentration of components such as nicotine volatilized from the smoking material 5 in the heating chamber 4 is substantially suppressed.
器具１は、加熱器３と加熱室４／喫煙材料５の間に配置された遮熱部３ａを備えてもよい。遮熱部３ａは、熱エネルギーが遮熱部３ａを通過して実質的に流れないように構成されており、したがってこの遮熱部３ａを用いると、加熱器３が活性化され熱エネルギーを放射しているときであっても、喫煙材料５を選択的に加熱されないようにすることができる。図１４を参照すると遮熱部３ａは、例えば加熱器３の周りに同軸に配置された熱反射材料の円筒状の層を備えてもよい。あるいは図１を参照して述べたように加熱器３が加熱室４および喫煙材料５の周りに配置されている場合は、遮熱部３ａは加熱室４の周りに同軸にかつ加熱器３の内部に同軸に配置された熱反射材料の円筒状の層を備えてもよい。遮熱部３ａは、加熱器３を喫煙材料５から隔離するように構成された断熱層を追加的にまたは代わりに備えてもよい。 The appliance 1 may comprise a heat shield 3a arranged between the heater 3 and the heating chamber 4/smoking material 5. The heat shield 3a is configured so that heat energy does not substantially flow through the heat shield 3a. Therefore, when the heat shield 3a is used, the heater 3 is activated and radiates heat energy. It is possible to prevent the smoking material 5 from being selectively heated even when it is being heated. With reference to FIG. 14, the heat shield 3a may comprise, for example, a cylindrical layer of heat-reflecting material arranged coaxially around the heater 3. Alternatively, when the heater 3 is arranged around the heating chamber 4 and the smoking material 5 as described with reference to FIG. 1, the heat shield 3 a is coaxial with the heating chamber 4 and of the heater 3. It may comprise a cylindrical layer of heat-reflecting material arranged coaxially therein. The heat shield 3a may additionally or alternatively include an insulating layer configured to isolate the heater 3 from the smoking material 5.
遮熱部３ａは実質的に熱透過性の窓３ｂを備える。窓３ｂによって熱エネルギーが窓３ｂを通って加熱室４および喫煙材料５に伝わるようになる。したがって、喫煙材料５の窓３ｂと整列している部分は加熱され、残りの部分は加熱されない。遮熱部３ａおよび窓３ｂは喫煙材料５に対して回転自在または可動式でもよいため、遮熱部３ａおよび窓３ｂを回転または移動させることによって喫煙材料５の異なる部分を選択的にかつ別々に加熱することができる。その効果は上記の加熱領域１０を選択的かつ別々に活性化させることにより得られる効果と同様である。例えば、遮熱部３ａおよび窓３ｂを吸引検出器１３の信号に応じて徐々に回転または移動させてもよい。加えてまたは代わりに遮熱部３ａおよび窓３ｂを所定の加熱経過時間で徐々に回転または移動させてもよい。遮熱部３ａおよび窓３ｂの移動または回転を制御器１２の電子信号で制御してもよい。遮熱部３ａ／窓３ｂと喫煙材料５の相対的な回転またはその他の移動を、制御器１２に制御されたステッピングモーター３ｃで駆動してもよい。これを図１４に説明している。あるいは遮熱部３ａおよび窓３ｂをハウジング７の作動装置のような使用者の制御を用いて回転させてもよい。遮熱部３ａは円筒状である必要はなく、必要なら適切に位置決めされた長手方向に延びる１つ以上の要素および／または板を構成してもよい。 The heat shield 3a includes a window 3b that is substantially heat permeable. The window 3b allows thermal energy to be transferred through the window 3b to the heating chamber 4 and the smoking material 5. Therefore, the portion of the smoking material 5 aligned with the window 3b is heated, and the remaining portion is not heated. Since the heat shield 3a and the window 3b may be rotatable or movable with respect to the smoking material 5, by rotating or moving the heat shield 3a and the window 3b, different portions of the smoking material 5 are selectively and separately separated. It can be heated. The effect is similar to the effect obtained by selectively and separately activating the heating region 10. For example, the heat shield 3a and the window 3b may be gradually rotated or moved according to a signal from the suction detector 13. Additionally or alternatively, the heat shield 3a and the window 3b may be gradually rotated or moved in a predetermined heating elapsed time. The movement or rotation of the heat shield 3a and the window 3b may be controlled by an electronic signal from the controller 12. The relative rotation or other movement of the heat shield 3a/window 3b and the smoking material 5 may be driven by the stepping motor 3c controlled by the controller 12. This is illustrated in FIG. Alternatively, the heat shield 3a and the window 3b may be rotated under the control of the user such as the actuator of the housing 7. The heat shield 3a need not be cylindrical, but may comprise one or more longitudinally extending elements and/or plates that are appropriately positioned if desired.
当然だが、加熱器３、遮熱部３ａ、および窓３ｂに対して喫煙材料５を相対回転または相対移動させても同様の結果を得ることができる。例えば、加熱室４が加熱器３周りに回転自在でもよい。この場合、遮熱部３ａの移動に関する上記の記述を、加熱室４の遮熱部３ａに対する相対移動の代わりに適用することができる。 Of course, the same result can be obtained by rotating or moving the smoking material 5 relative to the heater 3, the heat shield 3a, and the window 3b. For example, the heating chamber 4 may be rotatable around the heater 3. In this case, the above description regarding the movement of the heat shield 3a can be applied instead of the relative movement of the heating chamber 4 with respect to the heat shield 3a.
遮熱部３ａは加熱器３の長手方向表面の被覆を含んでもよい。この場合、加熱器表面の一部領域は被覆されず、熱透過窓３ｂを形成している。加熱器３を例えば制御器１２による制御または使用者による制御によって回転または移動させて、喫煙材料５の異なる部分を加熱することができる。代わりに遮熱部３ａおよび窓３ｂは独立した遮蔽部３ａを構成してもよい。この遮蔽部３ａは、制御器１２による制御またはその他の使用者による制御によって、加熱器３および喫煙材料５の両方に対し相対回転または相対移動することができる。 The heat shield 3a may include a coating on the longitudinal surface of the heater 3. In this case, a part of the surface of the heater is not covered and the heat transmission window 3b is formed. The heater 3 can be rotated or moved, for example under the control of the controller 12 or the control of the user, to heat different parts of the smoking material 5. Alternatively, the heat shield 3a and the window 3b may form an independent shield 3a. The shield 3a can be rotated or moved relative to both the heater 3 and the smoking material 5 under the control of the controller 12 or the control of another user.
器具１は吸気口１４を備えてもよい。吸気口１４によって、吸引中に外気をハウジング７内に吸引し、加熱された喫煙材料５内を通過させることができる。吸気口１４はハウジング７の開口１４を構成してもよく、喫煙材料５および加熱室４からハウジング７の第１の端部８に向かって上流に配置されてもよい。これを図１に示す。別の具体例を図６に示す。吸気口１４を通って吸引された空気は加熱された喫煙材料５内を移動し、その中で芳香蒸気のような喫煙材料の蒸気が混入され、その後吸い口６から使用者によって吸入される。必要なら図６に示す様に器具１は、喫煙材料５に入る前の空気を暖めるように、および／または吸い口６から吸引される前の空気を冷やすように構成された熱交換器１５を備えてもよい。例えば熱交換器１５は、吸い口６に入る空気から抽出された熱を用いて喫煙材料５に入る前の新しい空気を暖めるように構成されてもよい。 The device 1 may include an air inlet 14. The intake port 14 allows outside air to be sucked into the housing 7 during suction and passed through the heated smoking material 5. The air inlet 14 may constitute the opening 14 of the housing 7 and may be arranged upstream from the smoking material 5 and the heating chamber 4 towards the first end 8 of the housing 7. This is shown in FIG. Another specific example is shown in FIG. The air sucked through the intake port 14 moves through the heated smoking material 5 in which the vapor of the smoking material, such as aroma vapor, is mixed and then inhaled by the user through the intake port 6. If necessary, as shown in FIG. 6, the device 1 comprises a heat exchanger 15 configured to warm the air before entering the smoking material 5 and/or cool the air before being sucked from the mouthpiece 6. You may prepare. For example, the heat exchanger 15 may be configured to heat the fresh air prior to entering the smoking material 5 using heat extracted from the air entering the mouthpiece 6.
器具１は喫煙材料の圧縮器１６を備えてもよい。圧縮器１６は活性化されると喫煙材料５を圧縮するように構成されている。また器具１は喫煙材料の膨張器１７も備えることができる。膨張器１７は活性化されると喫煙材料５を膨張させるように構成されている。圧縮器１６および膨張器１７は実際には以下の説明のように同一の装置として実装されてもよい。喫煙材料の圧縮器１６および膨張器１７は制御器１２による制御によって必要に応じて作動してもよい。この場合、制御器１２は電気信号のような信号を圧縮器１６または膨張器１７に送るように構成されており、それによって圧縮器１６または膨張器１７がそれぞれ喫煙材料５を圧縮あるいは膨張させる。代わりに圧縮器１６および膨張器１７を器具１の使用者がハウジング７の手動式の制御によって起動して、喫煙材料５を必要に応じて圧縮または膨張させてもよい。 The device 1 may comprise a compressor 16 of smoking material. Compressor 16 is configured to compress smoking material 5 when activated . The device 1 may also include an inflator 17 of smoking material. The inflator 17 is configured to inflate the smoking material 5 when activated . Compressor 16 and expander 17 may actually be implemented as the same device, as described below. The smokable material compressor 16 and expander 17 may be activated as needed by control by the controller 12. In this case, the controller 12 is configured to send a signal, such as an electrical signal, to the compressor 16 or expander 17, which causes the compressor 16 or expander 17 to compress or expand the smoking material 5, respectively. Alternatively, the compressor 16 and expander 17 may be activated by the user of the device 1 by manual control of the housing 7 to compress or expand the smoking material 5 as needed.
基本的に圧縮器１６は、喫煙材料５を圧縮しそれによって加熱中の喫煙材料５の密度を上げるように構成されている。喫煙材料の圧縮により喫煙材料５の塊の熱伝導率が大きくなり、したがってニコチンおよび他の芳香成分のより急速な加熱、およびその結果生じる急速な揮発をもたらす。これは、使用者がニコチンおよび芳香剤を吸引の検出に応じて実質的な遅れなく吸入することができるようになることから好ましい。したがって、制御器１２は吸引の検出に応じて圧縮器１６を起動して、喫煙材料５を所定の加熱時間だけ、例えば１秒間圧縮してもよい。例えば制御器１２の制御の下で、所定の時間加熱したら喫煙材料５の圧縮を緩めるように圧縮器１６を構成してもよい。あるいは、喫煙材料５が所定の閾温度に達するのに応じて圧縮を緩めるか、あるいは圧縮を自動的に終了してもよい。適切な閾温度は約１５０〜２５０℃の範囲でもよく、使用者が選択できてもよい。温度感知器を用いて喫煙材料５の温度を検出してもよい。 Basically, the compressor 16 is configured to compress the smoking material 5 and thereby increase the density of the smoking material 5 during heating. The compression of the smoking material increases the thermal conductivity of the mass of smoking material 5, thus resulting in more rapid heating of the nicotine and other aroma components, and the resulting rapid volatilization. This is preferred because it allows the user to inhale nicotine and fragrance without substantial delay in response to detecting inhalation. Therefore, the controller 12 may activate the compressor 16 in response to the detection of suction to compress the smoking material 5 for a predetermined heating time, for example 1 second. For example, under the control of the controller 12, the compressor 16 may be configured to loosen the compression of the smoking material 5 after heating for a predetermined time. Alternatively, the compression may be relaxed or the compression may be terminated automatically in response to the smoking material 5 reaching a predetermined threshold temperature. A suitable threshold temperature may be in the range of about 150-250°C and may be user selectable. You may detect the temperature of the smoking material 5 using a temperature sensor.
基本的に膨張器１７は、喫煙材料５を膨張させそれによって吸引中の喫煙材料５の密度を下げるように構成されている。喫煙材料５が膨張すると、加熱室４内の喫煙材料５の配列はより疎らなる。すると、気体の流れ、例えば入り口１４から喫煙材料５を通過する空気の流れが容易になる。したがってこの空気は、揮発したニコチンおよび芳香剤を吸い口６にさらに運び、吸引に供することができる。制御器１２は、上記の圧縮時間の直後に膨張器１７を起動して喫煙材料５を膨張させ、空気がより自由に喫煙材料５を経由して吸引されるようにしてもよい。膨張器１７の起動と同時に可聴音を出し、あるいは他の表示をして、喫煙材料５が加熱されたことおよび吸引を開始できることを使用者に示してもよい。 Basically, the inflator 17 is configured to expand the smoking material 5 and thereby reduce the density of the smoking material 5 during inhalation. When the smoking material 5 expands, the arrangement of the smoking material 5 in the heating chamber 4 becomes more sparse. This facilitates the flow of gas, for example the flow of air from the inlet 14 through the smoking material 5. Therefore, this air can further carry the volatilized nicotine and the fragrance to the mouthpiece 6 and can be used for suction. The controller 12 may activate the inflator 17 to inflate the smoking material 5 immediately after the above-described compression time so that air is more freely drawn through the smoking material 5. An audible tone or other indication may be provided upon activation of the inflator 17 to indicate to the user that the smoking material 5 has been heated and that suction can begin.
図８および９を参照すると、圧縮器１６および膨張器１７はばね駆動の棒を備えてもよい。ばね力駆動の棒は、ばねが圧縮状態から開放されると加熱室４内の喫煙材料５を圧縮するように構成されている。これが図８および９に概略説明されている。ただし、当然だが他の実装法を用いることができる。例えば圧縮器１６は、上記の管状の加熱室４とほぼ等しい厚みを有する環を備え、この環がばねまたは他の手段によって加熱室４に押し込まれて喫煙材料５を圧縮してもよい。あるいは圧縮器１６を加熱器３の一部として構成し、加熱器３自身が制御器１２の制御の下で喫煙材料５を圧縮および膨張させるように構成されてもよい。喫煙材料５を圧縮および膨張させる一方法を図１０に示す。 With reference to FIGS. 8 and 9, compressor 16 and expander 17 may comprise spring driven rods. The spring-powered rod is arranged to compress the smoking material 5 in the heating chamber 4 when the spring is released from its compressed state. This is outlined in Figures 8 and 9. However, of course other implementations can be used. For example, the compressor 16 may comprise a ring having a thickness approximately equal to the tubular heating chamber 4 described above, which ring may be pushed into the heating chamber 4 by a spring or other means to compress the smoking material 5. Alternatively, the compressor 16 may be configured as a part of the heater 3, and the heater 3 itself may be configured to compress and expand the smoking material 5 under the control of the controller 12. One method of compressing and expanding the smoking material 5 is shown in FIG.
加熱器３は上述の断熱部１８と一体でもよい。例えば図１を参照すると、断熱部１８は実質的に細長い中空の本体を備え、例えば実質的に円筒状の管のような断熱部１８でもよい。この中空の本体は加熱室４の周りに同軸に配置されており、これに加熱領域１０が一体化されている。断熱部１８はある層を備え、この層に複数の凹みが設けられ、内向きの表面形状２１を成していてもよい。加熱領域１０はこれらの凹みに配置されているため、加熱領域１０は加熱室４内の喫煙材料５と面する。加熱室４に面する加熱領域１０の表面は、凹みがない断熱部１８の複数領域の内側表面２１と面一でもよい。 The heater 3 may be integrated with the heat insulating unit 18 described above. For example, referring to FIG. 1, the insulation 18 comprises a substantially elongated hollow body, which may be a insulation 18, such as a substantially cylindrical tube. The hollow body is coaxially arranged around the heating chamber 4 and the heating region 10 is integrated therein. The heat insulating part 18 may be provided with a certain layer, and this layer may be provided with a plurality of recesses to form an inwardly facing surface shape 21. The heating area 10 is arranged in these depressions, so that the heating area 10 faces the smoking material 5 in the heating chamber 4. The surface of the heating region 10 facing the heating chamber 4 may be flush with the inner surfaces 21 of the plurality of regions of the heat insulating portion 18 without depressions.
加熱器３と断熱部１８を一体化すると、喫煙材料加熱室４の方を向いている加熱領域１０の内向きの側部を除き、加熱領域１０の全ての側部が断熱部１８で実質的に取り囲まれることになる。そのようにして、加熱器３により放射される熱は喫煙材料５に集中し、器具１の他の部分またはハウジング７の外気中に消散しない。 When the heater 3 and the heat insulating part 18 are integrated, substantially all the side parts of the heating region 10 are the heat insulating part 18 except the inward side part of the heating region 10 facing the smoking material heating chamber 4. Will be surrounded by. In that way, the heat radiated by the heater 3 is concentrated in the smoking material 5 and does not dissipate in the outside air of the rest of the appliance 1 or the housing 7.
また加熱器３を断熱部１８と一体にすると、加熱器３と断熱部１８の組み合わせの厚みを減らすこともできる。このようにすると器具１の直径、具体的にはハウジング７の外径をさらに減らすことができる。あるいは、加熱器３と断熱部１８の一体化して厚みを低減するとさらに広い喫煙材料加熱室４を器具１に収容することができ、あるいはハウジング７の全幅を少しも広げることなく追加的な要素を取り入れることができる。 Further, if the heater 3 is integrated with the heat insulating unit 18, the thickness of the combination of the heater 3 and the heat insulating unit 18 can be reduced. In this way, the diameter of the device 1, specifically the outer diameter of the housing 7, can be further reduced. Alternatively, if the heater 3 and the heat insulating part 18 are integrated to reduce the thickness, a wider smoking material heating chamber 4 can be accommodated in the device 1, or additional elements can be added without expanding the entire width of the housing 7. Can be incorporated.
あるいは、加熱器３を断熱部１８と一体にするのではなく、断熱部１８に隣接させてもよい。例えば、加熱器３を加熱室４の外側に配置する場合、フィルム加熱器３で断熱部１８の内向き表面２１を覆ってもよい。加熱器３を加熱室４の内部に配置する場合は、フィルム加熱器３で断熱部１８の外向き表面２２を覆ってもよい。 Alternatively, the heater 3 may be adjacent to the heat insulating unit 18 instead of being integrated with the heat insulating unit 18. For example, when the heater 3 is arranged outside the heating chamber 4, the film heater 3 may cover the inward surface 21 of the heat insulating portion 18. When the heater 3 is disposed inside the heating chamber 4, the film heater 3 may cover the outward surface 22 of the heat insulating portion 18.
必要なら、加熱器３と断熱部１８の間に障壁が在ってもよい。例えばステンレス鋼の層が加熱器３と断熱部１８の間に在ってもよい。この障壁は、加熱器３と断熱部１８の間に収まるステンレス鋼管を備えてもよい。障壁の厚みは器具の寸法を実質的に大きくしないように薄くてもよい。一例示的厚みは約０．１〜１．０ｍｍである。 There may be a barrier between the heater 3 and the insulation 18 if desired. For example, a layer of stainless steel may be present between the heater 3 and the thermal insulation 18. This barrier may comprise a stainless steel tube that fits between the heater 3 and the insulation 18. The barrier thickness may be thin so as not to substantially increase the size of the device. One exemplary thickness is about 0.1-1.0 mm.
また、複数の加熱領域１０の横断面の間に熱反射層が在していてもよい。各加熱領域１０の１つから放射される熱エネルギーが隣の加熱領域１０を実質的に加熱しないが加熱領域１０の周囲表面から主に内向きに加熱室４と喫煙材料５に移動するように、複数の加熱領域１０を相対的に配置してもよい。各加熱領域１０は他の領域１０と実質的に同じ寸法を有してもよい。 Further, a heat reflection layer may be present between the cross sections of the plurality of heating regions 10. So that the thermal energy radiated from one of each heating zone 10 does not substantially heat the adjacent heating zone 10 but moves mainly inwardly from the peripheral surface of the heating zone 10 into the heating chamber 4 and the smoking material 5. The plurality of heating regions 10 may be arranged relatively. Each heating zone 10 may have substantially the same dimensions as the other zones 10.
加熱器３を器具１内に感圧接着剤を用いて接着または固定してもよい。例えば加熱器３を上記の断熱部１８または障壁に感圧接着剤を用いて接着してもよい。あるいは加熱器３をカートリッジ１１または喫煙材料加熱室４の外面に接着してもよい。 The heater 3 may be bonded or fixed within the device 1 using a pressure sensitive adhesive. For example, the heater 3 may be bonded to the heat insulating portion 18 or the barrier by using a pressure sensitive adhesive. Alternatively, the heater 3 may be adhered to the outer surface of the cartridge 11 or the smoking material heating chamber 4.
感圧接着剤を使用する代わりに、自己溶融テープを用いて加熱器３を器具１内の所定位置に固定してもよく、または所定位置に固定する締め具で固定してもよい。これらの方法の全てによって加熱器３を確実に固定することができ、加熱器３から喫煙材料５に熱を効率的に伝達することが可能になる。他の種類の固定も可能である。 Instead of using a pressure sensitive adhesive, the heater 3 may be fixed in place within the device 1 using a self-melting tape, or it may be fixed with fasteners that hold it in place. By all of these methods, the heater 3 can be securely fixed, and heat can be efficiently transferred from the heater 3 to the smoking material 5. Other types of fixation are possible.
上記のように喫煙材料５とハウジング７の外面１９との間に設けられている断熱部１８によって器具１からの熱損失が減り、したがって喫煙材料５が加熱される効率が改善する。例えば図１を参照すると、ハウジング７の壁が、加熱室４の外周周りに延びている断熱部１８の層を備えてもよい。断熱層１８の長さは、実質的に加熱室４および喫煙材料５の周りに同軸に配置された断熱部１８の管長でもよい。これを図１に示す。なお、断熱部１８を喫煙材料カートリッジ１１の一部として構成することができ、この場合断熱部１８は喫煙材料５の外側に同軸に配置されることになる。 As mentioned above, the thermal insulation 18 provided between the smoking material 5 and the outer surface 19 of the housing 7 reduces heat loss from the device 1 and thus improves the efficiency with which the smoking material 5 is heated. For example, referring to FIG. 1, the wall of the housing 7 may be provided with a layer of thermal insulation 18 extending around the outer circumference of the heating chamber 4. The length of the heat insulating layer 18 may be a tube length of the heat insulating portion 18 arranged coaxially around the heating chamber 4 and the smoking material 5. This is shown in FIG. It should be noted that the heat insulating portion 18 can be configured as a part of the smoking material cartridge 11, and in this case, the heat insulating portion 18 is arranged coaxially outside the smoking material 5.
図１１を参照すると、断熱部１８は真空断熱部１８を構成してもよい。例えば断熱部１８は金属材料のような壁材料１９で囲まれた層を構成してもよい。断熱部１８の内部領域すなわち中心部２０は、例えば重合体、エアロゲル、または他の適切な材料を含む連続気泡性の多孔質材料を備え、低圧に減圧されていてもよい。内部領域２０内の圧力は０．１〜０．００１ミリバールの範囲でもよい。断熱部１８の壁１９は、中心部２０と壁１９の外面の間の圧力差によって壁１９に働く力に耐えるだけ十分に強く、それによって断熱部１８がつぶれないようにしている。例えば壁１９は約１００μｍの厚みを有するステンレス鋼の壁１９を備えてもよい。断熱部１８の熱伝導率は０．００４〜０．００５Ｗ／ｍＫの範囲でもよい。断熱部１８の熱通過率は約１５０〜約２５０℃の温度範囲で約１．１０〜約１．４０Ｗ／（ｍ２Ｋ）でもよい。断熱部１８の気体の伝導率は無視できる。壁材料１９の内面に反射被覆を施して、断熱部１８を介した放射伝搬による熱損失を最小にしてもよい。この被覆には例えば約０．３〜１．０μｍの厚みを有するアルミニウムＩＲ反射被覆を含んでもよい。中心領域２０内が減圧状態であれば、中心領域２０の厚みが非常に薄い場合でも断熱部１８が機能することになる。この断熱特性は実質的にその厚みに影響されない。このことにより器具１全体を小さくすることが容易になる。 Referring to FIG. 11, the heat insulating unit 18 may form a vacuum heat insulating unit 18. For example, the insulation 18 may comprise a layer surrounded by a wall material 19, such as a metallic material. The interior region or core 20 of the insulation 18 may comprise an open celled porous material including, for example, a polymer, airgel, or other suitable material, and may be depressurized to a low pressure. The pressure in the inner region 20 may be in the range of 0.1-0.001 mbar. The wall 19 of the insulation 18 is strong enough to withstand the forces exerted on the wall 19 by the pressure difference between the central portion 20 and the outer surface of the wall 19, thereby preventing the insulation 18 from collapsing. For example, the wall 19 may comprise a stainless steel wall 19 having a thickness of about 100 μm. The thermal conductivity of the heat insulating portion 18 may be in the range of 0.004 to 0.005 W/mK. The heat transfer coefficient of the heat insulating part 18 may be about 1.10 to about 1.40 W/(m 2 K) in the temperature range of about 150 to about 250°C. The gas conductivity of the heat insulating portion 18 can be ignored. A reflective coating may be applied to the inner surface of the wall material 19 to minimize heat loss due to radiation propagation through the thermal insulation 18. The coating may include, for example, an aluminum IR reflective coating having a thickness of about 0.3-1.0 μm. If the inside of the central region 20 is in a reduced pressure state, the heat insulating portion 18 will function even if the thickness of the central region 20 is very thin. This insulating property is virtually independent of its thickness. This facilitates making the entire instrument 1 smaller.
図１１に示す様に、壁１９は内向き部分２１および外向き部分２２を備えてもよい。内向き部分２１は実質的に喫煙材料５および加熱室４と向き合う。外向き部分２２は実質的にハウジング７の外側と向き合う。器具１の作動中、内向き部分２１は加熱器３の熱エネルギーによってより温かくてもよく、外向き部分２２は断熱部１８の影響によって冷たい。内向き部分２１および外向き部分２２は、例えば実質的に平行で長手方向に延び加熱器３と少なくとも同じ長さの複数の壁１９を構成してもよい。外向き壁部２２の内面すなわち減圧された中心領域２０に面している表面は中心部２０内の気体を吸収する被覆を備えてもよい。適切な被覆は酸化チタン膜である。 As shown in FIG. 11, the wall 19 may include an inward facing portion 21 and an outward facing portion 22. The inward facing portion 21 substantially faces the smoking material 5 and the heating chamber 4. The outwardly facing portion 22 substantially faces the outside of the housing 7. During operation of the appliance 1, the inward part 21 may be warmer due to the thermal energy of the heater 3 and the outward part 22 is cold due to the influence of the thermal insulation 18. The inward-facing portion 21 and the outward-facing portion 22 may, for example, constitute a plurality of walls 19 that are substantially parallel and extend longitudinally at least as long as the heater 3. The inner surface of the outwardly facing wall 22, that is, the surface facing the depressurized central region 20, may be provided with a coating that absorbs gas within the central portion 20. A suitable coating is a titanium oxide film.
断熱部１８は、米国特許第７，３７４，０６３号に記載のインスロン（登録商標）成形真空熱障壁（Insulon Shaped-Vacuum Thermal Barrier）のような超高真空断熱部を備えてもよい。そのような断熱部１８の総厚みは極めて薄くてもよい。一例示的厚みは約１ｍｍ〜約１μｍ、例えば約０．１ｍｍである。但し、他のもっと厚いまたは薄い厚みも可能である。断熱部１８の断熱特性は実質的にその厚みの影響を受けず、したがって器具１からの熱損失を実質的に少しも増やすことなく薄い断熱部１８を用いることができる。非常に薄い断熱部１８によって、ハウジング７および器具１全体を先に述べた大きさより小さくできるようにしてもよく、器具１の厚み例えば直径を、紙巻きタバコ、葉巻、および細巻き葉巻のような喫煙品とほぼ等しくすることができるようにしてもよい。また、器具１を軽量化して上記の小型化と同様の利点を提供してもよい。 The insulation 18 may comprise an ultra-high vacuum insulation such as the Insulon® Shaped-Vacuum Thermal Barrier described in US Pat. No. 7,374,063. The total thickness of such thermal insulation 18 may be very thin. One exemplary thickness is about 1 mm to about 1 μm, for example about 0.1 mm. However, other thicker or thinner thicknesses are possible. The thermal insulation properties of the thermal insulation 18 are substantially independent of its thickness, so that a thin thermal insulation 18 can be used without substantially increasing the heat loss from the device 1. A very thin insulation 18 may allow the housing 7 and the device 1 as a whole to be smaller than the sizes mentioned above, the thickness of the device 1 e.g. the diameter being determined by smoking such as cigarettes, cigars and cigars. It may be possible to make it almost equal to the product. Also, the instrument 1 may be made lighter to provide the same advantages as the downsizing.
上記の断熱部１８は気体吸収材料を備えて中心領域２０内の真空の維持または真空化を容易にしてもよいが、気体吸収材料は高真空断熱部１８には用いられない。気体吸収材料がないことは断熱部１８の厚みを非常に薄く保つことの助けとなり、すなわち器具１全体を小さくすることが容易になる。 Although the thermal insulation 18 may include a gas absorbing material to facilitate maintaining or evacuating the vacuum in the central region 20, the gas absorbing material is not used for the high vacuum thermal insulation 18. The absence of gas-absorbing material helps to keep the thickness of the insulation 18 very thin, i.e. making the overall appliance 1 smaller.
超高断熱部１８の形状によって、断熱部の真空度を製造中に断熱部１８の中心領域２０から分子を抽出するのに用いられる真空よりも上げることができる。例えば断熱部１８の内部の高真空を、それを作る真空炉室の真空度より高くすることもできる。断熱部１８の内部の真空は例えば１０−７トール程度でもよい。図１６を参照すると、高真空断熱部１８の中心領域２０の一端は先細りし、外向き部分２２および内向き部分２１が出口２５に収束するようになっており、断熱部１８の製造中に出口２５を通って中心領域２０内の気体が除去されて高真空が作られるようになっていてもよい。図１６には外向き部分２２が内向き部分２１の方に収束するように説明されているが、内向き部分２１が外向き部分２２に収束する逆の配置を代わりに用いることができる。断熱壁１９の収束端は中心領域２０内の気体分子を出口２５の外に出し、それによって中心部２０の高真空を作るように構成されている。出口２５は封止式で、領域２０の減圧後に中心領域２０の高真空を維持する。出口２５の封止は、例えば中心部２０から気体を除去した後に出口２５のろう付け材料を加熱して出口２５にろう付け封止を作ることで封止することができる。別の密封技術を用いることもできる。 The shape of the ultra-high insulation 18 allows the vacuum of the insulation to be higher than the vacuum used to extract molecules from the central region 20 of the insulation 18 during manufacturing. For example, the high vacuum inside the heat insulating portion 18 can be made higher than the vacuum degree of the vacuum furnace chamber in which it is made. The vacuum inside the heat insulating unit 18 may be, for example, about 10 −7 Torr. Referring to FIG. 16, one end of the central region 20 of the high-vacuum insulating portion 18 is tapered so that the outward portion 22 and the inward portion 21 are converged to the outlet 25. Gas in central region 20 may be removed through 25 to create a high vacuum. Although FIG. 16 illustrates that the outwardly facing portion 22 converges toward the inwardly facing portion 21, the reverse arrangement in which the inwardly facing portion 21 converges at the outwardly facing portion 22 may be used instead. The converging end of the adiabatic wall 19 is configured to drive gas molecules in the central region 20 out of the outlet 25, thereby creating a high vacuum in the central portion 20. The outlet 25 is sealed and maintains a high vacuum in the central region 20 after depressurizing the region 20. The outlet 25 can be sealed, for example, by removing gas from the center 20 and then heating the braze material at the outlet 25 to create a braze seal at the outlet 25. Other sealing techniques can be used.
中心領域２０を減圧するために、断熱部１８を実質的に減圧された低圧の環境内、例えば真空炉室中に置いて、中心領域２０内の気体分子が断熱部１８の外の低圧環境に流れ込むようにしてもよい。中心領域２０内の圧力が低下すると、中心領域２０の先細りした形状および具体的には上記の収束部２１、２２が、残留気体分子を出口２５経由で中心部２０から出すのに影響するようになる。特に、中心領域２０内の気体の圧力が低いときは、中心部２０内の残留気体分子を出口２５へ導き、中心部２０から気体が出ていく可能性を低圧環境の外部から気体が中心部２０に入る可能性よりも高くするのに、収束している内向き部分２１および外向き部分２２の案内効果は有効である。この方法では、中心部２０の形状によって中心部２０内の圧力を断熱部１８の外の環境の圧力よりも低圧にすることができる。 In order to reduce the pressure in the central region 20, the heat insulating portion 18 is placed in a substantially reduced pressure and low pressure environment, for example, in a vacuum furnace chamber, so that gas molecules in the central region 20 are exposed to a low pressure environment outside the heat insulating portion 18. You may make it flow. As the pressure in the central region 20 decreases, the tapered shape of the central region 20 and specifically the converging portions 21, 22 described above affect the exit of residual gas molecules from the central portion 20 via the outlet 25. Become. In particular, when the pressure of the gas in the central region 20 is low, the residual gas molecules in the central portion 20 are guided to the outlet 25, and the possibility that the gas may come out of the central portion 20 is reduced by the gas from the outside of the low pressure environment. The guiding effect of the converging inward portion 21 and outward portion 22 is effective in making it more likely to enter 20. In this method, the pressure inside the central portion 20 can be made lower than the pressure of the environment outside the heat insulating portion 18 depending on the shape of the central portion 20.
必要なら上記の様に、１種以上の低放射率被覆が壁１９の内向き部分２１および外向き部分２２の内面に存在して、放射による熱損失を実質的に防止してもよい。 If desired, one or more low emissivity coatings may be present on the inner surfaces of the inwardly facing portion 21 and the outwardly facing portion 22 of the wall 19 to substantially prevent radiative heat loss, as described above.
断熱部１８の形状を本明細書では全体に実質的に円筒状または類似の形状であると述べたが、断熱部１８を別の形状にして、例えば種々の形状および大きさの加熱室４、加熱器３、ハウジング７、またはエネルギー源２のような種々の構成の器具１を収容し断熱することも可能である。例えば、上記のインスロン（登録商標）成形真空熱障壁のような高真空断熱部１８の大きさおよび形状には、実質的にその製造過程による制限はない。上記の集束構造の形成に適切な材料にはセラミック、金属、半金属、およびこれらの組合せがある。 Although it has been stated herein that the shape of the heat insulating part 18 is substantially cylindrical or similar in general, the heat insulating part 18 may have another shape, for example, the heating chamber 4 having various shapes and sizes, It is also possible to house and insulate various configurations of the appliance 1, such as the heater 3, the housing 7, or the energy source 2. For example, the size and shape of the high vacuum insulation 18, such as the Inslon® molded vacuum thermal barrier described above, is not substantially limited by its manufacturing process. Suitable materials for forming the focusing structure described above include ceramics, metals, metalloids, and combinations thereof.
図１２の概略説明を参照すると、断熱部１８の１つ以上の端部において熱橋２３によって内向き壁部２１と外向き壁部２２を接続して、低圧の中心部２０を完全に取り囲み収容してもよい。熱橋２３は内向き部分２１および外向き部分２２と同じ材料で形成された壁１９を備えてもよい。適切な材料は上述のようにステンレス鋼である。熱橋２３は断熱中心部２０よりも大きな熱伝導率を有し、したがって不都合なことに熱を器具１から外に伝えてしまうことがあり、その際に喫煙材料５を加熱する効率が低下する。 12, a thermal bridge 23 connects the inward wall 21 and the outward wall 22 at one or more ends of the insulation 18 to completely enclose and house the low pressure center 20. You may. The thermal bridge 23 may include a wall 19 formed of the same material as the inward facing portion 21 and the outward facing portion 22. A suitable material is stainless steel as described above. The thermal bridge 23 has a greater thermal conductivity than the adiabatic core 20 and thus may undesirably transfer heat away from the device 1, in which case the efficiency of heating the smoking material 5 is reduced. ..
熱橋２３による熱損失を減らすため、熱橋２３を延長して内向き部分２１から外向き部分２２への熱の流れに対する抵抗を大きくしてもよい。これを図１３に概略説明する。例えば熱橋２３は壁１９の内向き部分２１と壁１９の外向き部分２２の間の遠回りの経路を進んでもよい。これを、長手方向のある距離にわたって断熱部１８を設けることによって容易にしてもよい。この距離は、熱橋２３が内向き部分２１から外向き部分２２まで遠回りの経路に沿って徐々に延びることができるように加熱器３、加熱室４、および喫煙材料５の長さよりも長い。そうすることによって、加熱器３、加熱室４、および喫煙材料５がないハウジング７の長手方向のある場所では、中心部２０の厚みがゼロになる。 In order to reduce the heat loss due to the heat bridge 23, the heat bridge 23 may be extended to increase resistance to heat flow from the inward portion 21 to the outward portion 22. This will be outlined in FIG. For example, the thermal bridge 23 may follow a circuitous path between the inwardly facing portion 21 of the wall 19 and the outwardly facing portion 22 of the wall 19. This may be facilitated by providing the insulation 18 over some distance in the longitudinal direction. This distance is longer than the length of the heater 3, the heating chamber 4 and the smoking material 5 so that the thermal bridge 23 can gradually extend along the circuitous path from the inward portion 21 to the outward portion 22. By doing so, the thickness of the central portion 20 becomes zero at some location in the longitudinal direction of the housing 7 without the heater 3, the heating chamber 4, and the smoking material 5.
図１５を参照すると上記のように、断熱部１８で断熱された加熱室４は閉じると加熱室４を封止する吸排気弁２４を備えてもよい。弁２４はそのようにして室４への空気の不必要な出入りを防ぎ、喫煙材料の香りが室４から出ないようにすることができる。吸排気弁２４を例えば断熱部１８に設けてもよい。例えば吸引と吸引の間は弁２４を制御器１２で閉じ、その間は揮発した物質が室４内に留まるようにしてもよい。吸引と吸引の間の揮発物質の分圧は飽和蒸気圧に達し、したがって蒸発物質の量は加熱室４内の温度だけで決まる。これにより吸引から吸引まで、揮発したニコチンおよび芳香成分の確実な一定供給が促進される。吸引中、制御器１２は弁２４を開けるように構成されており、空気が室４を通って流れて揮発した喫煙材料成分を吸い口６に運ぶことができるようになっている。室４に酸素が絶対入らないようにする膜を弁２４内に配置することができる。弁２４を呼気起動式にして、吸い口６の吸引の検出に応じて弁２４が開くようにしてもよい。弁２４は吸引終了の検出に応じて閉じてもよい。あるいは弁２４はその開放後に所定時間が経過したら閉じてもよい。この所定時間を制御器１２で計時してもよい。必要なら機械式または他の適切な開放／閉鎖手段を設けて、弁２４が自動的に開いたり閉じたりするようにしてもよい。例えば使用者による吸い口６の吸引で生じる気体の移動を用いて弁２４を開けたり閉めたりしてもよい。したがって弁２４の起動に制御器１２の使用は必ずしも必要ではない。 As described above with reference to FIG. 15, the heating chamber 4 insulated by the heat insulating unit 18 may be provided with an intake/exhaust valve 24 that closes the heating chamber 4 when closed. The valve 24 can thus prevent unnecessary entry and exit of air into the chamber 4 and prevent the smoking material scent from leaving the chamber 4. The intake/exhaust valve 24 may be provided in the heat insulating unit 18, for example. For example, the valve 24 may be closed by the controller 12 between suctions, and the volatilized substance may remain in the chamber 4 during that time. The partial pressure of the volatiles between the suctions reaches the saturated vapor pressure, so that the amount of the vaporized material is determined only by the temperature in the heating chamber 4. This promotes reliable and constant supply of volatilized nicotine and aroma components from suction to suction. During inhalation, the controller 12 is configured to open the valve 24 so that air can flow through the chamber 4 to carry the volatilized smoking material component to the mouthpiece 6. A membrane can be placed in the valve 24 which ensures that no oxygen enters the chamber 4. The valve 24 may be an exhalation start type, and the valve 24 may be opened in response to the detection of the suction of the mouthpiece 6. The valve 24 may be closed upon detection of the end of suction. Alternatively, the valve 24 may be closed after a predetermined time has elapsed since its opening. This predetermined time may be timed by the controller 12. Mechanical or other suitable opening/closing means may be provided if desired to allow the valve 24 to open and close automatically. For example, the valve 24 may be opened or closed by using the movement of gas generated by the suction of the suction port 6 by the user. Therefore, the use of controller 12 is not necessary to activate valve 24.
加熱器３、例えば各加熱領域１０で加熱される喫煙材料５の質量は０．２〜１．０ｇの範囲でもよい。喫煙材料５が加熱される温度は使用者が制御可能でもよく、その温度は例えば上記のような１５０〜２５０℃の温度範囲内の任意の温度でもよい。器具１全体の質量は７０〜１２５ｇの範囲でもよいが、フィルム加熱器３および／または高真空断熱部１８を採用する場合は軽くすることができる。容量が１０００〜３０００ｍＡｈで電圧が３．７Ｖの電池２を用いることができる。加熱領域１０は、１つのカートリッジ１１の喫煙材料５の約１０〜４０の部分を別々にかつ選択的に加熱するように構成されていてもよい。 The mass of the smoking material 5, eg the smoking material 5 heated in each heating zone 10, may be in the range of 0.2 to 1.0 g. The temperature at which the smoking material 5 is heated may be controllable by the user, and the temperature may be any temperature within the temperature range of 150 to 250° C. as described above. The overall mass of the device 1 may be in the range of 70-125 g, but can be lighter if the film heater 3 and/or the high vacuum insulation 18 is employed. A battery 2 having a capacity of 1000 to 3000 mAh and a voltage of 3.7 V can be used. The heating region 10 may be configured to separately and selectively heat about 10-40 portions of the smoking material 5 of one cartridge 11.
